WAGON.

Application led February 17, 1917.

To all whom` it may concern.'

Be it known that I, CARL CHnIsTiANsoN, a citizen of the United States7 residing at Deerfield, in the county of Dane and State .of liVisconsin, have invented certain useful Improvements in lVagons, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates t0 Wagons, and more particularly to the class of self-loading wagons.

The primary object of the invention is the provision of a wagon of this character wherein the body thereof is of novel formation so that the capacity in the loading thereof can be increased or decreased and the extending of the body is automatically controlled and regulated by the operator.

AnotherY object of the invention is the provision of a Wagon of this character wherein the body thereof is so constructed that on the filling of the same from a loader the material fed to the body is delivered on to a movable section thereof which is ad vanccd so that the body in its entirety will be, completely lled to its caoacity, thereby eliminating manual labor in istributing the material, as is usual.

A further object of the invention is the provision of a wagon of this character wherein the movable section of its body is automatically controlled from the power of the traction Wheels and said section can be reversely moved for effecting the proper and full loading of the body.

A still further object of the invention is the provisionof a Wagon of this character whichV is simple in construction, thoroughly reliable and efticient in operation, strong, durable and inegpensive in manufacture.

Other objects will be in part obvious and art hereinafter set forth.

he invention accordingly consists in the features of construction, combination of elements and arrangement of parts Which will be exemplifiedrin the construction hereinafter described, and the scope of the application of which `vvil be indicated inthe appended claims.

In the accompanying drawings:

Figure 1 is a top an view of a VWagon constructed in accor ance with the inventien;

Fig 2 is a side elevation thereof;

Fig. a vertical longitudinal sectional view through the wagon;

serial No. 149,322.

Fig. 4 is a sectional view on the line 4 1 of Fig. 1;

Fig. 5 is a sectional view on the line 5 5 of Fig. 1;

Fig. 6 is a rear elevation of the Wagon;

Fig. 7 is a front elevation thereof;

Fig. S is an enlarged fragmentary vertical longitudinal sectional View through the gear control.

Similar reference characters indicate corresponding parts throughout the severai views of the drawings.

Referring to the drawings in detail, A designates generally a body; B, the supporting truck; C, the front traction wheels and D the rear traction wheels of the Wagon hereinafter fully described.

The truck B comprises spaced parallel side rails 10, a front end cross rail 1l and rear end rails 1Q, the side rails 10 and end rails being fastened to each other in any suitable manner to provide a rigid frame structure. Located below the front cross rail 11 of the truck B are the front running gear holsters 13 which carry the king bolt 14and mounted upon one of these holsters is the front axle 15 supporting the front Wheels C, while extending forwardly of the front running gear is the usual draft tongue 16 for the attachment of draft animals, although the tongue 16 can be dispensed With and in lieu thereof a suitable couplin for a traction engine. The front Wheels are of a size to permit the movement thereof beneath the truck B for the effective turning of the wagon, as Will be apparent.

The rear axle 17 carrying the rear Wheels D is jonrnaled in boxings or bearings 18 lixed to and depending from the. side rails 10 of theE truck B, and these side rails of said truck have permanently fixed'thereto V the stationary section 19 of the body A. and this section 19 extends for the full length of the truck. while the movable section 20 is mounted upon and is designed to travel longitudinally upon the said stationary section 19 in the manner presently described and for a purpose hereinafter set forth.

TheVst-ationary and movable sections 19 andV .20 of the body A carry side boards 21 and incline toward eachother, the side boards being supported upon suitable brackets or stanchions 22 which prevent the sagging thereof and rigidly hold the same in place.

Mounted' on the rear axle l? for vertical swinging movement are gear housings or easings 23 which are elongated and have journaled therein the rack gearing 24 Ineshing with gears 25 fixed to the rear axle 17, and connected with these housings or casings 23 for unitary movement thereof is an operating mechanism which includes a lever 2G adapted to be manually manipulated by the operator of the wagon for shifting the gear housings or easings Q3 for a purpose presently described. Secured to the under side of the movable section 20 in longitudinal alinement with the gearing 2-1- are rack bars 2T with which are adapted to mesh the outermost gears 24 on the adjustment of the housings or casings 23 for the automatic shifting of the movable section Q0 either forwardly or rearwardly at the option of the operator of the wagon. The lever 26 is manually thrown to shift the housings or casin Jr 23 to bring the particular outermost pair of gears into mesh with the rack bars 27 for the shifting of the movable section Q0 of the body in the direction desired.

The stationary section 19 of the body at the bottom thereof has mounted therein suitable friction rollers 28 which permit the free movement. of the movable section 2() when shifted.

0n the rear end of the stationary section 19 and the forward end of the movable section 20 are racks 29 for sustaining the material when fed to the body of the Wagon from a loader of any approved type.

The forward portion of the truck B has mounted thereon additional friction rollers 28 for the movable section Q0 of the body.

At the front end of the truck B is suitably supported a drivers seat 30 to be occupied by the driver or operator of the wagon. At the front end of the movable section Q0 at the corners thereof are depending props or legs 31 which have suitable shoes 3Q at their lower ends. which are elevated slightly from the ground and serve to steady the load when the movable section 20 has been shifted forwardly with its load, although it is to be understood that these props or supports can be dispensed with and are only desirable at side hills.

ln the use of the wagon the same can be automatically loaded by a loading` machine and is designed particularly for the carriage of hay or corn, although any other material can be transported thereby, and in the use of said wagon the necessity of hand loading is eliminated. which requires considerable work or labor as in the hand pitching of the material into the body of the Wagon the same has to be distributed in a uniform manner for the proper loading thereof, and in the use of an automatic loader the material delivered therefrom becomes massed or stacked at the rear. end of the Wagon body so that by reason of the use of the movable section the wagon body can he loaded expeditiously and with minimum labor.

The stationary section 19 of the wagon body is formed with slots 33 for the proper meshing of the gears Q4 in the housings or casings Q3 with the rack bars Q7 on the movable section of said body, as will be obvious.

It is of course to be understood that changes, variations and modifications may be made in the invention such as come properly within the scope of the appended claims without departing from the spirit of the in.- vention or sacrificing any of its advantages. Each rack bar 27 has in its opposite faces longitudinal grooves in which are loosely engaged L-shapcd retaining members which are suitably connected to the rear axle 17, and these members prevent the raising of the movable section :20 when the gears 2l are shifted by the ope iator, thereby assuring the meshing of the gear with the rack bar and avoiding any possible displacement of the movable section which would interfere with the movement thereof in changing the position of the same.

From the foregoing description, taken in connection with the accompanying drawing, the construction and manner of use of the herein described Wagon will be readily apparent and, therefore, a more extended explanation has been omitted.

Having thus described my invention, I claim:

1, In a Wagon, a body formed in two sections one of which is stationary With the other movable thereon, a running gear having a rotating rear axle and on Which the body is mo nnted, a longitudinal rack on each side of the movable section, gear trains having their driving units mounted on the said rear axle, casings angularly movable on the rear axle and supporting the remaining units of the gear trains, each gear train being engageable with one of the racks on the movable section by either one or another of its individual units, and means for effecting the angular movement of the casings Whereby the one or the other of these said units of the gear trains is made to mesh with the racks.

2. In a wagon, a body formed in two sections one of which is stationary with the other movable thereon, a ruiming gear having a rotating rear axle and on which the body is mounted, a longitudinal rack on each side of themovable section, L-shaped retaining members carried by the rear axle and positively but slidably engaging the racks to retain the movable section on the stationary section, casings mounted on the rear axle and angularly movable thereon with the center of said axle as a pivot, a driving gear Within each casing and positively connected with the said rear axle, gear trains carried by the casings and driven by the aforesaid driving gears, two units of each train being engageable one or the other with oneI of the longitudinal ranks, and means for simultaneously eleeting the angular movement of the easings, whereby the movable section of the body may be moved in either direction irrespective of the direction of movement of the rear axle.

3. In a wagonha body formed in two seetions one of which is stationary with the other movable thereon, a running gear having a rotating rear axle and on which the body is mounted, a longitudinal rack on each side of the movable section, anti-friction rollers uniformly spaced along the stationary section and supporting the movable seetion throughout the length of its movement, L-shaped retaining members carried by the rear axle of the running gear and positively but slidably engaging the racks to retain the movable section on the anti-friction rollers,

easings mounted on the rear axle and angularly movable thereon with the center of said axle as a pivotA` a driving gear within each easing and positively connected with the said axle, gear trains carried by the easings and driven by the aforesaid driving gears, two units of each train being engageable one or the other with one of the longitudinal racks, a latch controlled hand lever mounted at the forward end of the stationf ary section, and Connections between the said hand lever and the said angularly movable easings, whereby the one or the other unit of each gear train may be raised to effect its ineshing with its attendant longitudinal: rack to permit the movable section to be moved rearwardly or forwardly irrespective of the direction of movement of the said rear axle of the running gear.

In testimony whereof I affix my signature.

CARL CHRISTIANSON.
